Growing up an army brat

I grew up on military bases and in embassies and there were a few things that I thought were normal - chocolate from army composite ration packs which was just a slab of dairy milk with the NATO stock number on it. One other thing was that my Dad (who'd done the MI6 photography training) would often borrow a work OM1 and snap family pictures and then they'd get processed in the embassy lab. So, here is a picture of me, on a sledge, with an MI6 reference number and the word restricted on it! Have I just broken the official secrets act?!
